Understanding Human Karyotyping
What is Human Karyotyping?
Human karyotyping involves the microscopic examination of chromosomes, which are thread-like structures composed of DNA and proteins. Typically, a human somatic cell contains 46 chromosomes, arranged in 23 pairs. These pairs include 22 autosomes and 1 pair of sex chromosomes (XX or XY). The process involves culturing cells, arresting them in metaphase during cell division, staining the chromosomes, and then analyzing their structure and number.
Traditional Techniques in Karyotyping
Historically, karyotyping has relied on:
- Cell culture and synchronization
- Chromosome arrest using colchicine or colcemid
- Staining methods such as Giemsa (G-banding)
- Microscopic imaging with light microscopes
- Manual pairing and classification of chromosomes
While effective, this approach is labor-intensive and subject to human error, especially during the manual identification and classification phases.
